Axonal Remapping Quote by Robert M. Sapolsky
““Axonal remapping in blind or deaf individuals is great, exciting, and moving. It’s cool that your hippocampus expands if you drive a London cab. Ditto about the size and specialization of the auditory cortex in the triangle player in the orchestra. But at the other end, it’s disastrous that trauma enlarges the amygdala and atrophies the hippocampus, crippling those with PTSD. Similarly, expanding the amount of motor cortex devoted to finger dexterity is great in neurosurgeons but””
